A two–constraints kinematic fit is utilized to extract the top quark, either b-jet the ones that is recognizable or it is not recognizable. It is shown that for point LM1, for the former situation, a 5σ excess can be achieved with 30 pb-1 and for the latter situation, it can be observed with 9.6 pb-1. The ratio of the final signal over background for both situations is 12.0. A search for SUSY using the top quark plus missing transverse energy (MET), in a low mass mSUGRA test point is performed.
